Subject: [PATCH 02/15] md-cluster: Improve another size determination in
 resync_info_update()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 1 Oct 2016 11:37:24 +0200

Replace the specification of a data structure by a variable name
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer.
